The low-cost Sprint MVNO FreedomPop just launched its freemium phone service last month, but now it's expanding phone selection by letting users bring their own handsets. However, that doesn't mean you can take just any Sprint device over the FreedomPop and kiss your bill goodbye – there are some restrictions.

Spending too much on your phone service? You could maybe cut that bill down a bit, if you're willing to make a few sacrifices. How does free sound? FreedomPop, which previously started offering free mobile and home internet access, is expanding into phone service. For $0 per month, you can get 200 voice minutes, 500 texts, and 500MB of 3G/4G data.

This is obviously not a plan for heavy data users, but 500 MB might be workable if you're on WiFi most of the day.

In a post to the Android Building group earlier today, Jean-Baptiste Queru announced that Samsung's Nexus S 4G has officially and fully been brought into the AOSP fold. The device is now fully supported by AOSP, meaning its CDMA – and WiMax – binaries can now be "properly" distributed. Here's the full text of the announcement:

We've been able to resolve the issues around Nexus S 4G, and we can now properly distribute its CDMA and WiMAX binaries.

Sprint has long been the refuge for data-hungry users that don't want to deal with caps or overages. While Sprint's regular 3G and 4G data usage on phones is still unlimited, back in October the Now Network started capping the mobile hotspot feature at 5GB per month. Starting last Friday, May 18th, that plan is gone. In its place are two pricier options.

The low-end option comes with 2GB of monthly bandwidth and costs $19.99 per month.

If you've been looking to jump ship from the carrier juggernauts and get in on Sprint's promised "truly unlimited data", may we suggest now might be a good time to do so? From now until March 26th, all of Sprint's 4G phones (read: Sprint's best phones) are available for a penny with a new activation. Sorry upgraders.

Update 4/20/12: All Sprint Android phones are free again thanks to the Sprint Through Spring promotion...

It's only been a couple years since the EVO launched as not only the first WiMax phone, but the first "4G" phone (by carrier reckoning). Now, though, Sprint says that not only will there be no more WiMax phones, which we knew earlier, but no more WiMax devices at all. That means hotspots and tablets will also lack any WiMax antennae. Don't worry, though. Sprint has promised 15 LTE devices by year's end.

Sprint posted its fourth quarter earnings this morning, and they definitely painted a mixed picture of the company's financial position. On the one hand, the Alamo of unlimited data increased its subscriber base by 1.6 million in the last quarter, with big thanks likely owed to the addition of the iPhone to Sprint's lineup - giving them a significant advantage over their primary price point rival, T-Mobile.

Unfortunately, also because of the iPhone, the company managed a $1.3 billion net loss for the quarter, owed in large part to the massive cost of providing the device ($15.5 billion over 4 years) to customers at heavily subsidized price points.

It would appear that Sprint plans on going full speed ahead in focusing on product development for its 4G LTE lineup this year. David Owens, Sprint's VP of Product Development made clear at CES Wednesday that Sprint "won't be introducing any more WiMax smartphones," adding "April, May, June, July, August, those will be very aggressive times for us." This may be a hint that we could begin seeing LTE devices as early as April, which is great news for customers holding out for a new device (like Samsung's Galaxy Nexus, which is poised to be Sprint's first LTE device).

Update: Dow Jones Newswires apparently left out a key piece of information from Hesse's statement on throttling, in an example of truly stellar journalism and attention to detail (unfortunately, we have no audio or video record to verify Hesse's statements). Hesse was discussing throttling of those who are on networks that Sprint has roaming agreements with (which, admittedly, Sprint has a lot of - including with Verizon). While this still makes Sprint's ads technically misleading, the throttling really only applies to those who live in areas where Sprint's data network relies chiefly on roaming - not to those using primarily Sprint towers.

And so it begins - Android Police's First Annual Mega-Holiday Giveaway Series. For the next ten days, you'll have chances to win all sorts of awesome Android phones, tablets, and other goodies. (As a note to our international readers, this first contest features prizes that don't work outside the US, but don't worry, we have some more stuff coming for you later today.)
